BRADFORD ROWE, OF MARYLAND, NEXV YORK.

BOOT-CRIMP.

Specification of Letters Patent No. 2,8785, dated December 17, 1842.

To all whom it may concern Be it known that I, BRADFORD Rows, ofMaryland, in the county of Otsego and State of New York, have invented anew and useful Improvement in Machines for Crimping Boot-Fronts, whichis described as follows, reference being had to the annexed drawings ofthe same, making part of this specication:

Figure l is a perspective view of the machine.

A represents the bench; B, the center stationary jaw; C, the movableside jaws; D, the brass lining or covering of the jaws; E, the screw forclosing the jaws; F, a crimping lever with a single arm, pair ofpincers, windlass, and straps-with a boot front strained thereon andthrown back from the jaws in a position to be disengaged from the bench,a joint on which it turns; H, the boot front; I, the pincers; J, thestrap; K, the axle; L, ratchet wheel; M, the pawl.

F2 is a crimp lever with a combination of arms, pincers, straps, axles,ratchets and pawls and a boot front strained on the lever and broughtbetween the jaws.

N2 are the combined arms; I2, the pincers for taking hold of the edgesof the leather; J2, the straps attached to the pincers and wound aroundthe windlasses; K2, the windlasses; L2, the ratchet wheels and M2 thepawls; O, the winch for turning the axles or windlasses; P, the screwsfor closing the jaws of the pincers, C2, the joint on which the crimpinglever turns.

To use this machine the leather should first be prepared as for anycrimping mapincers I are then fastened to the edges of the leather anddrawn out from the jaws by the windlasses which are held by the ratchetsand pawls. The crimping lever is Vthen thrown back on the joint C2 fromthe jaws C and disengaged from the bench by'withdrawing the pin G2 andlaid aside for the leather to dry thereon in its crimped state, andanother crimping lever and straining apparatus put in the place thereofOr the crimping lever may be suffered to remain attached to the benchuntily the leather be dried. By the use of the aforesaid combinedpincers and removable crimping lever the boot front may be strained atthe points required without the necessity of tacking the leather and maybe dried on the lever on which it is crimped.

I/Vhat I claim as my invention and which I desire to secure by LettersPatent is- The combination of the pincers with the removable crimp asconstructed and operated in the manner herein set forth.

BRADFORD ROI/VE.
